Glossary of Engineering Machinery Hydraulic Pumps and Travel Final Motor Drives

Hydraulic Pump (液压泵): Converts mechanical power into hydraulic power. Typically installed within the hydraulic system of the excavator. Example: Hitachi EX200-5 Main Pump, Part Number: 9147291.
Travel Final Drive (行走终传动): Reduces the high-speed, low-torque output of the travel motor to the low-speed, high-torque required to drive the excavator's tracks. Located in the undercarriage, connected to the tracks. Example: Komatsu PC200-8 Travel Motor, Part Number: 708-2L-00300.
Gear Pump (齿轮泵): A type of positive displacement pump that uses meshing gears to pump fluid by displacement. Commonly used in auxiliary hydraulic systems. Example: Generic Gear Pump, Part Number: CB-F3.2.
Axial Piston Pump (轴向柱塞泵): A type of hydraulic pump that uses reciprocating pistons in a rotating cylinder block to move fluid. Often used as the main hydraulic pump in excavators. Example: Caterpillar 320D Main Pump, Part Number: 244-3347.
Radial Piston Pump (径向柱塞泵): Another type of positive displacement pump where pistons move radially within a cylinder block. Used in applications requiring high pressure. Example: Rexroth Radial Piston Pump, Part Number: R902103123.
Swing Motor (回转马达): Provides the rotational motion for the excavator's upper structure. Mounted on the undercarriage, responsible for turning the cab and boom. Example: Kobelco SK200-8 Swing Motor, Part Number: YS36V0004F1.
Orbit Motor (摆线液压马达): A type of hydraulic motor that uses an internal gear and an external rotor to produce rotary motion. Used for various auxiliary functions. Example: Eaton Orbit Motor, Part Number: 104-1007-006.
Hydraulic Motor (液压马达): Converts hydraulic power back into mechanical power, used to drive various components like tracks and swing mechanism. Installed in different parts of the excavator depending on the function. Example: Generic Hydraulic Motor, Part Number: BMH-200.
Vane Pump (叶片泵): A type of rotary positive displacement pump that pumps fluid using vanes mounted on a rotor that rotate inside a cavity. Often used for power steering systems. Example: Vickers Vane Pump, Part Number: 20V2U-17-1R.
Reduction Gear (减速齿轮箱): Part of the final drive assembly that reduces the motor speed and increases torque. Located within the travel final drive unit. Example: Generic Reduction Gear, Part Number: RDG-500.

General Knowledge about Engineering Machinery

Regular maintenance of hydraulic systems is crucial for the longevity and performance of excavators. Checking hydraulic fluid levels and inspecting for leaks can prevent costly downtime.
The efficiency of the engine directly impacts the fuel consumption of heavy machinery. Ensuring the engine is running optimally through regular servicing can lead to significant cost savings.
Proper selection of ground engagement tools (GET), such as bucket teeth, can significantly improve the productivity and efficiency of excavating and loading operations.

Engine Troubleshooting Tip: Overheating

Symptom: Engine temperature gauge shows excessively high readings, accompanied by possible steam or coolant leaks.

Possible Causes and Solutions:

Low Coolant Level: Check the coolant level in the radiator and coolant reservoir. Add the recommended coolant mixture if the level is low. Inspect for any leaks in hoses, radiator, or water pump.
Faulty Thermostat: The thermostat regulates the flow of coolant through the engine. If it's stuck closed, the engine can overheat. Consider replacing the thermostat.
Radiator Blockage: The radiator fins may be clogged with dirt, debris, or insects, reducing its ability to dissipate heat. Clean the radiator fins with compressed air or a gentle stream of water.
Water Pump Failure: A malfunctioning water pump may not circulate coolant effectively. Listen for unusual noises from the water pump. If suspected, have it inspected and possibly replaced.
Loose or Damaged Fan Belt: The fan belt drives the engine cooling fan. A loose or damaged belt can cause the fan to rotate improperly, leading to overheating. Inspect the fan belt for wear and tear and adjust or replace as needed.

If the overheating issue persists after checking these common causes, it is recommended to consult a qualified mechanic.
